The external discharge port 15 or the internal discharge port 16 is switched depending on the state of No. 4. The liquid discharged from the internal discharge port 16 is returned to the container 2 through the water purification means 17 containing activated carbon and the like. The circulation means 18 drives the pump 11, and is driven by the circulation control means 19. When the operation knob 20 installed on the upper surface of the main body 1 is operated, the contact of the switch 21 linked with the operation knob 20 is switched, and the circulation control means 19 drives the circulation means 18 by the signal. At this time, the operation knob 2

すると、循環制御手段１９に信号を出力する。The conductivity of the liquid depends on the amount of ions contained in the liquid, and the conductivity increases as the amount of calc (Cl) contained in the liquid increases. From the conductivity, the concentration of scaly and other substances contained in the liquid can be known.
That is, the water quality is determined by comparing the conductivity measured by the electrode 8 with a predetermined value, and if it is determined that the scaly or the like has been removed, a signal is output to the circulation control means 19.

１９は循環手段１８にオフ信号を出力する。The circulation control means 19 confirms the signal from the water quality judgment means 9, and if the signal is a signal in which the scaly is not sufficiently removed, it outputs an ON signal to the circulation means 18 to drive the pump 11. If the operation knob 20 is not operated here, the state of the valve 14 in the water channel switching means 13 is on the internal outlet 16 side, and therefore the container 2 discharged from the discharge port 10 by driving the pump 11 is operated. The liquid inside passes through the water conduit 12 and flows from the internal discharge port 16 to the water purifying means 1.
Impurities such as chlorine are removed by 7 and returned to the container 2. Further, when the signal from the water quality judging means 9 becomes a signal from which scaly or the like is sufficiently removed, the circulation control means 19 outputs an off signal to the circulation means 18.

Especially, the conductivity increases as the amount of calc (Cl) contained in the liquid increases, so the water quality judging means 9 uses this conductivity. The rate indicates the concentration of scaly and other substances contained in the liquid.

When the user has many components such as scaly, it can be reheated to reduce the amount of scaly and can be used with confidence. In the present embodiment, the water quality indicator 22 uses an LED, but a buzzer may be used to make a beep several times when the concentration of bleaching or the like falls below a predetermined value to notify the user. The effect can be obtained.
